Arrhoges Paleocaenica

Original Comment of Rosenkrantz, 1970 about Arrhoges (Latiala) palaeocaenica:

"This new subgenus of Sohl (1960, p. 101) has hitherto only been met with in the uppermost Cretaceous but has a late representative in the Upper Danian of West Greenland showing a somewhat similar sculpture, a terminal thickening of the outer lip and no internal grooving of the lip. The Danian species differs from the Cretaceous species in having the bilobation of the outer lip less marked, in having a shorter rostrum and some faint spiral sculpture on body and whorls."
